Prominent anterior and posterior clinoid processes lead to traumatic internal carotid artery aneurysm following craniofacial injury

摘要

Traumatic intracranial aneurysms are rare, comprising 1% or less of all cerebral aneurysms. Theydevelop after blunt or penetrating head trauma. We present a 50-year-old patient in whom subarachnoidhemorrhage was developed as a result of traumatic aneurysm rupture after a closed craniofacial trauma. Throughthe careful evaluation of the three-dimensional computed tomography and conventional angiographies, thepossible mechanism of the traumatic internal carotid artery (ICA) trunk aneurysm is correlated with a hit injuryby the prominent anterior and posterior clinoid processes. This vulnerable traumatic ICA aneurysm wassuccessfully obliterated with clipping and wrapping technique. The clinical presentation and possible underlyingmechanism are discussed with a review of pertinent literature
